Performance
<Compelling performance: with vs. without MIC>
<Competitive performance, if available>
<How much each of original host code and code with MIC was sped up (e.g. Xeon 1.3x, MIC 2.2x)>
<List of optimizations that yielded perf improvements, how much each gave (order dependent), why I thought that’d help, and how generalizable I think such optimization is>
